anyone whether the fuel filter inlet hose on a 91 318is is molded or not? none of the parts on realoem look like what's in my car, and the inlet hose looks molded to me. having nothing else to go on, i ordered #5 from bmw on this diagram:

I don't know the answer to your question, however I would ask does the hose have to be moulded? As long as there's enough space to run a piece of generic hose to both barbs without it getting kinked I would say that it doesn't have to be moulded. You might have to run the hose slightly differently than factory but it'll be cheaper to buy a length of hose off the spool at NAPA or wherever than buying a custom moulded hose from BMW.

ya, that's my exact problem: a generic hose looks like it might get kinked if i try to route it exactly like the current hose, which appears to be factory. if i can't find the correct hose, i might be forced to reposition the filter to clear an unkinked generic route.

just finished the install. managed a decent routing. no leaks, runs fine. the hose i installed had to run from the tank hard line directly to the fuel filter inlet because at some point before i bought the car someone removed #7 here:

that length would have been too short for my routing, but the elbow would have been nice going into the filter, assuming the remainder is as flexible as a normal fuel hose. interesting that your 318is is also missing #7. maybe they all shipped without it and the realoem diagram is wrong.

IIRC the length was about 10 inches, I'll check under the car if you're still unsure.

Sometimes the realoem diagrams are generic but what's listed below is usually what came on the car, if you entered the VIN correctly? It's always good to double check the part number on ecstuning.com and blunttech.com (they have a lot of pictures).
